随着人口的增长和经济的发展，自然资源利用的增加对流域造成了严重的破坏。洪水、山体滑坡和干旱等自然灾害的影响变得更加频繁。Cisadane集水区是印度尼西亚108个重点流域之一。SWAT目前在世界范围内得到应用，被认为是一种多功能模型，可用于整合多种环境过程，从而支持更有效的流域管理和制定更明智的政策决策。本研究的目的是检验SWAT模型在山地流域建模中的适用性，重点是印度尼西亚西爪哇省的Cisadane流域。SWAT模型模拟是在2005 - 2010年期间进行的，而它使用的是2009年的土地利用信息。序贯不确定性拟合方法。本研究采用2 （SUFI2）和人工校准相结合的方法对一次降雨径流进行了校准。2007年进行了校准，2009年进行了验证，校准的R2和Nash Sutchliffe效率（NSE）分别为0.71和0.72，验证度分别为0.708和0.7。模拟的月平均地表径流量和总产水量分别为27.7 mm和2718.4 mm。该研究表明swat模型可以作为一种潜在的监测工具，特别是在西沙丹流域或热带地区的流域。该模型可用于其他目的，特别是在流域管理中。关键词模型，SWAT, SUFI2，流域，水文学，西沙丹。提交：2013年11月27日更正：2013年12月20日接受：2014年1月4日Doi: 10.12777/ijse.6.1.12-21[如何引用本文：Ridwansyah， I., Pawitan， H., Sinukaban， N., and Hidayat， Y. 2014。]ArcSWAT和SUFI2在Cisadane流域的流域建模：河流流量预测的校准与验证。科学与工程学报，6(2):12-21。Doi: 10.12777 / ijse.6.2.12-21
Increasing of natural resources utilization as a result ofpopulation growthandeconomic developmenthas causedseveredamage on the watershed. The impactsof naturaldisasterssuch asfloods, landslides anddroughtsbecome more frequent. Cisadane Catchment Area is one of 108 priority watershed in Indonesia.SWAT is currently applied worldwide and considered as a versatile model that can be used to integrate multiple environmentalprocesses, which support more effective watershed management and the development of betterinformed policy decision. Theobjective of this study is to examine the applicability of SWAT model for modeling mountainous catchments, focusing on Cisadane catchment Area in west Java Province, Indonesia. The SWAT model simulation was done for the periods of 2005 – 2010 while it used landuse information in 2009. Methods of Sequential Uncertainty Fitting ver. 2 (SUFI2) and combine with manual calibration were used in this study to calibrate a rainfall-runoff. The Calibration is done on 2007 and the validation on 2009, the R2 and Nash Sutchliffe Efficiency (NSE) of the calibration were 0.71 and 0.72 respectively and the validation are 0.708 and 0.7 respectively. The monthly average of surface runoff and total water yield from the simulation were 27.7 mm and 2718.4 mm respectively.This study showedSWAT model can be apotential monitoring tool especially for watersheds in Cisadane Catchment Area or in the tropical regions. The model can be used for anotherpurpose,especiallyin watershed management. Keyword Model, SWAT, SUFI2, watershed, Hydrology, Cisadane.
